Power flushing is the professional cleaning and treatment of your central heating system, helping to remove magnetite sludge, rust, and debris that naturally build up over time. Although heating systems are designed to last between 15 and 20 years, this buildup can cause corrosion, reduce heat transfer, and lead to poor performance, which often shortens the life of the system.
Using powerful flushing equipment and specialist chemicals, our qualified engineers restore system efficiency by improving water flow and ensuring your radiators and boiler operate at maximum potential. A power flush is highly recommended before fitting a replacement boiler, as it guarantees a clean system, prevents future blockages, and delivers consistent heating throughout your home.
